Electrical Specifications

Unless otherwise specified V

DD

= 4.75V to 5.5V for the ISL705AEH/BEH/CEH, V

DD

= 3.15V to 3.6V for the

ISL706AEH/BEH/CEH T

A

= -55°C to +125°C. Boldface limits apply over the operating temperature range, -55°C to +125°C; over a total ionizing dose of

100krad(Si) with exposure at a high dose rate of 50 - 300krad(Si)/s; and over a total ionizing dose of 50krad(Si) with exposure at a low dose rate of

<10mrad(Si)/s.
